The Physical Oceanography Distributed Active Archive Center (PO.DAAC) released the NASA-SSH Sea Surface Height Indicators datasets produced by NASA. Four distinct datasets are released. The indicator values were calculated using data from the NASA-SSH Simple Gridded Sea Surface Height from Standardized Reference Missions Only Version 1 dataset (doi.org/10.5067/NSREF-SG0V1). Learn more about the NASA-SSH project.
The four datasets are: Global Mean Sea Level (GMSL), El Nino-Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Pacific Decadal Oscillation (PDO) sea surface height indicators. Indicator values were calculated using cyclostationary empirical orthogonal functions on the input data. The data begin in Oct. 1992 and continue through the present. Files for all indicator datasets are distributed in text format.
The data are available in the Earthdata catalog.
